Dynamics 365 Finance & Operations specialists

We design, build and support Dynamics 365 Finance & Operations.

Codefine is an İstanbul-based team of D365 F&O consultants and X++ developers. We have worked on Dynamics AX and Dynamics 365 projects for more than 20 years — rollouts, integrations, slow month-end batches, and the support that comes after go-live.

What we do

Six areas cover most of our work

Each one is handled by people who understand the business process and the X++, SQL and integrations underneath it.

All 10 services

  • 01

    D365 F&O Solution Architecture

    The technical and functional blueprint for D365 F&O — modules, data, integrations, security and extensions decided before they become expensive to change.

  • 02

    ERP Implementation & Configuration

    Module setup, data migration, testing and go-live for finance, procurement, warehouse, manufacturing and project operations.

  • 03

    Support & Managed Services

    Incident handling, monitoring, batch and integration health, service-update validation and continuous improvement after go-live.

  • 04

    Performance Optimization

    Slow forms, batch jobs, reports and integrations traced to their cause in X++, SQL, data volume or batch design — then fixed.

  • 05

    Custom Software Development

    Upgrade-safe X++ extensions, data entities, services and batch processes — plus connected .NET and Power Platform components.

  • 06

    Integration & API Development

    OData, custom services, business events, recurring data jobs and Azure Integration Services — designed for volume, failure and monitoring.

How we work

You work directly with the people doing the work

No layers of account management. The consultants and developers in the first conversation are the ones who read your code, check the query plans and join the cutover call. We work alongside your IT team and key users, on projects, on ongoing support, or both.

  • Architecture reviews and fit-gap before configuration starts
  • X++ extensions, data entities and integrations built on Microsoft's extension model
  • Performance work on forms, batch jobs, reports and SQL
  • Support after go-live, including testing each Microsoft service update

Engineering

We work in the code, not just the configuration

Plenty of D365 problems can only be fixed in X++, SQL or the integration layer. That is where most of our time goes.

  • X++

    Extensions, Chain of Command, SysOperation batch services and set-based data access.

  • SQL

    Query plans, index design, blocking chains and data-volume growth.

  • Data models

    Legal entities, financial dimensions and master data ownership.

  • Integrations

    OData, custom services, business events and Service Bus queues.

  • Batch jobs

    Batch groups, threads, task bundling and scheduling windows.

  • Architecture

    Upgrade-safe extension strategy, environments and ALM.

  • Azure

    Logic Apps, Functions, API Management and DevOps pipelines.

  • Power Platform

    Dataverse, virtual tables, dual-write and governed flows.

class CFInvoiceSyncService extends SysOperationServiceBase
{
    public void process(CFInvoiceSyncContract _contract)
    {
        CustInvoiceJour invoice;

        // Fetch only the fields the integration needs
        while select RecId, InvoiceId, InvoiceAccount from invoice
            where invoice.InvoiceDate == _contract.parmInvoiceDate()
        {
            CFInvoiceEvent::newFromInvoice(invoice).send();
        }
    }
}

Performance

When D365 is slow, we find out why

A slow posting can be X++ logic, one bad query, a lock held by a batch job or a call to another system. We measure first, then fix the part that is actually slow.

  • Slow forms

    Heavy data sources, display methods and grids that load more than they show.

  • SQL queries

    Scans where a seek was expected, missing indexes and parameter-sensitive plans.

  • Batch processing

    Serialised tasks, competing jobs and overnight runs that drift into the morning.

  • Reports

    Report data providers that read row by row and temporary tables that grow.

  • X++ execution paths

    Queries inside loops, missing set-based operations and caching that never hits.

  • Integration bottlenecks

    Synchronous calls in posting logic and entities processed one record at a time.

How projects run

The same team from first workshop to support

Nobody hands your project over to a different team after go-live.

  1. 01

    Understand

    We map business processes, pain points, the current system landscape and what success has to look like.

    • Process & landscape map
    • Prioritised requirements

  2. 02

    Architect

    We define the D365 F&O solution model: modules, data, integrations, security, environments and performance.

    • Solution blueprint
    • Integration & data design

  3. 03

    Deliver

    We configure, develop, test and deploy with clear ownership, controlled releases and go-live readiness checks.

    • Configured environments
    • Tested extensions & integrations

  4. 04

    Optimize

    We measure how the system behaves under real load and remove bottlenecks in code, queries and batch design.

    • Performance findings
    • Targeted fixes

  5. 05

    Support

    We stay after go-live: incident handling, monitoring, change requests and continuous improvement.

    • Managed support
    • Improvement backlog

Experience

20+ years across every version of Dynamics

From AX 4.0 to today's cloud Finance & Operations. That history helps when you are upgrading from AX or maintaining code someone wrote ten years ago.

  1. 2006

    Dynamics AX 4.0

    Axapta becomes Microsoft Dynamics AX. X++ and the AOT are the core of ERP customisation.

  2. 2008

    Dynamics AX 2009

    Role centres and a broader functional footprint across finance, trade and production.

  3. 2011

    Dynamics AX 2012

    Model store, new data model and the R2/R3 releases that many companies still run today.

  4. 2016

    Dynamics 365 for Operations

    The cloud generation: browser client, Lifecycle Services and Azure-hosted environments.

  5. 2019

    Finance & Supply Chain apps

    Continuous service updates and an extension-only model replace overlayering for good.

  6. Today

    Modern Microsoft ERP

    F&O converging with Power Platform, Dataverse, Fabric and Copilot capabilities.

Milestones are Microsoft's public product history, not individual Codefine projects.
